(a) In General. - Whoever -
(1) forcibly assaults, resists, opposes, impedes, intimidates,
or interferes with any person designated in section 1114 of this
title while engaged in or on account of the performance of
official duties; or
(2) forcibly assaults or intimidates any person who formerly
served as a person designated in section 1114 on account of the
performance of official duties during such person's term of
service,
shall, where the acts in violation of this section constitute only
simple assault, be fined under this title or imprisoned not more
than one year, or both, and where such acts involve physical
contact with the victim of that assault or the intent to commit
another felony, be fined under this title or imprisoned not more
than 8 years, or both.
(b) Enhanced Penalty. - Whoever, in the commission of any acts
described in subsection (a), uses a deadly or dangerous weapon
(including a weapon intended to cause death or danger but that
fails to do so by reason of a defective component) or inflicts
bodily injury, shall be fined under this title or imprisoned not
more than 20 years, or both.

Based on title 18, U.S.C., 1940 ed., Secs. 118, 254 (Mar. 4,
1909, ch. 321, Sec. 62, 35 Stat. 1100; May 18, 1934, ch. 299, Sec.
2, 48 Stat. 781).
This section consolidates sections 118 and 254 with changes in
phraseology and substance necessary to effect the consolidation.
Also the words "Bureau of Animal Industry of the Department of
Agriculture" appearing in section 118 of title 18, U.S.C., 1940
ed., were inserted in enumeration of Federal officers and employees
in section 1114 of this title.
The punishment provision of section 254 of title 18, U.S.C., 1940
ed., was adopted as the latest expression of Congressional intent.
This consolidation eliminates a serious incongruity in punishment
and application.
